Taylor Swift has penned another break-up song - and the speculation is that it's about her ex, Calvin Harris.
It's emerged that Better Man, the song released by country band Little Big Town, was written by Taylor.
The track tells the story of a jealous ex-boyfriend, and Little Big Town's lead singer Karen Fairchild said that it was "really special" to the singer.
Lyrics include: "But your jealousy, I can hear it now/You're talking down to me like I'll always be around.
"You push my love away like it's some kind of loaded gun/Boy, you never thought I'd run."
Another verse goes: "I know I'm probably better off all alone/Than needing a man who could change his mind at any given minute/And it's always on your terms."
It ends: "We might still be in love, if you were a better man."
Sources told The Sun that it's not a "huge leap" to imagine that the song is a dig at the superstar DJ, who she had a relationship with before hooking up with actor Tom Hiddleston.
The source was quoted as saying: "Her split from Tom Hiddleston in September was more amicable and happened just before the song came out, so he probably needn't worry.
"Calvin is her only other known boyfriend since she released 1989 in 2014. His ears must be burning now."
Calvin recently released a video for My Way, in which he relives a romance with a robotic ex.
